Purified Water System from NEWater

NEWater’s purification water systems are built under the careful supervision of environmental engineers, allowing us to achieve our goal of protecting our precious water and reducing wastewater discharge and water waste while recycling water. Our purified water systems are used in a wide range of applications in the biological, pharmaceutical, and automotive fields.

NEWater’s water purification systems utilize reverse osmosis technology, as well as other water treatment processes to treat water. Reverse osmosis technology uses a high-pressure pump to allow water to overcome its osmotic pressure and pass through a partially permeable membrane that retains impurities and allows clean water to pass through with a final resistivity that can approach 18.3 MΩ*cm. We also use multiple filtrations, ion exchange, de-aeration, reverse osmosis, ultraviolet light, ultrafiltration, nano-rate, and ion adsorption filtrations to produce ultra-pure water.

The water eventually obtained has no hardness and a sweeter taste, also often called softened water, and the produced water has almost no impurities, not to mention bacteria, viruses, chlorinated dioxins, and other organic substances, and can be consumed directly or boiled for drinking.

➣Which Water Purification Technologies Are Used in Purified Water Systems?

The need for alternative water sources has inspired the development and advancement of various water purification technologies. The extensive array of technologies makes it possible to purify contaminated water from various reserves. Quite often, two or more technologies are assimilated to attain high water purity levels. Let us walk through the frequently utilized purified water systems.

● Advanced membrane treatment.

Membrane treatment extracts undesirable impurities from raw water using mechanisms such as size exclusion or charge exclusion. There are over four membrane filtration processes utilized distinctively in varying water purification exercises. Underneath is a description of the three primary membrane treatment processes.

● Reverse osmosis.

Reverse osmosis is a pressure-based water purification technology that separates undesirable pollutants from water using partially porous membranes. Typical reverse osmosis membrane filters have perforations, which measure approximately 0.0001 microns. As such, they filter out fine molecules, unlike the other membrane filters. Reverse osmosis is mainly deployed to minimize the concentration of dissolved solids in water. It can shrink dissolved salt levels by 95% to 99.7%.

● Ultrafiltration.

Ultrafiltration is also a pressure-driven technology dependent on semi-permeable membranes. Its membrane pores are however not as microscopic as those in reverse osmosis. Typical ultrafiltration membrane filters have porosities measuring roughly 0.005–0.1 μm.  As such, they are more suited to extracting suspended solids and other high-molecular-weight pollutants.

● Nanofiltration.

Just like reverse osmosis and ultrafiltration, nanofiltration is driven by pressure to separate objectionable impurities from water using partially permeable membranes. Nanofiltration is primarily utilized in water softening due to its impeccable ability to extract divalent and trivalent ions. It is also quite popular in wastewater treatment due to its low energy consumption compared to reverse osmosis.

● Distillation.

Water distillation generates purified water by boiling raw water to the point of evaporation. Due to the discrepancy in boiling points, most contaminants are left behind as the water turns into vapor. Subsequently, the vaporized water is chilled in a condenser to produce liquefied distilled water. Distillation is widely used in saltwater desalination, drinking water purification, and well water treatment.

● Water deionization.

Water deionization is a process that draws out dissolved ions from water by exchanging them with non-pollutant ions. Typically, the water is deionized by the cation exchange resin and the anion exchange resin. In the cation exchange resin, the positively-charged pollutant ions are attracted by the anionic active sites. Hydrogen (H+) ions are subsequently discharged and they replace the objectionable ions. In the anion exchange resin, cationic active sites attract the negatively-charged ions, while hydroxyl (OH-) is released to substitute them.

➣What Are the Main Advantages of Purified Water Systems?

Purified water generation systems play an integral role by augmenting purified water supply and accessibility. Investing in a purified water system does not only benefit the user, it equally benefits the ecosystem and its inhabitants. It benefits the environment by minimizing the amount of pollution in water bodies and averting the overexploitation of natural freshwater reserves.

To the user, a purify water system provides high-level purified water economically and conveniently. They are affordably priced and they do not incur exorbitant production expenses.

➣What Are the Main Types of Purified Water Systems?

In response to the diverse demands of different application fields, manufacturers produce varying types of purification water systems. Our extensive pool of equipment covers industrial, residential, and commercial fields. Here is a brief description of the most-coveted purified water systems.

● Media filtration systems.

Media filtration systems purify water by filtering out objectionable impurities using distinct layers of media. There are varying kinds of media filtration systems that can be exploited distinctively in different water purification applications.

● Multimedia filters.

Multimedia filters are filtration systems deployed to shrink the level of turbidity and suspended solids in water. They are made of several layers of different media configured in order of size and porosity. Primarily, they consist of three layers; anthracite, sand, and garnet. However, the layers can have over three media.

● Pressure sand filters.

Pressure sand filters only utilize one filtration medium; sand. They however consist of several layers of sand configured in respect to specific gravity and size. They eliminate suspended matter and turbidity just like multimedia filters although they are not as effective.

● Carbon filters.

Carbon filters utilize powdered block carbon or granular activated carbon to trap contaminants. Activated carbon filters employ adsorption technology to extract suspended matter as well as chemical pollutants. They also remove organic chemicals that give water an awful smell and taste.

● Membrane filtration systems.

Membrane filtration systems filter out contaminants using semipermeable membranes. There are four advanced membrane filtration systems whose fields of application cut across different types of feed waters and sectors.

● Reverse osmosis systems.

Reverse osmosis systems consist of high-pressure pumps, which generate pressure to force the feed water through the partially permeable membranes. They expel contaminants such as dissolved salts, minerals, microorganisms, and organic compounds.

● Ultrafiltration systems.

Similar to reverse osmosis systems, ultrafiltration systems extract impurities using semipermeable membranes and are also pressure-driven. Nonetheless, their membrane perforations are relatively larger, hence they are primarily used to remove suspended solids and turbidity.

● Water deionizer systems.

Water deionizer systems generate deionized water, which is a distinct grade of purified water. They employ ion exchange technologies and extract nearly all dissolved ions from water. We manufacture two types of water deionizer systems;

• Two-bed deionizers.
• Mixed-bed deionizers.

● Reverse osmosis di water systems.

Reverse osmosis di water systems are hybrid water purification systems that incorporate reverse osmosis and water deionization processes. Reverse osmosis removes microorganisms, minerals, and suspended solids while deionization expels ionic impurities. R0/DI water systems are mainly used in laboratories and pharmaceuticals.

➣How Much Do Purified Water Systems Cost?

The cost of acquiring purified water systems has been shrinking over the years thanks to advancements in production technologies. The equipment’s price is however subjective depending on parameters such as size, design, purification technology, and construction material. At NEWater, our pricing strategy is mainly informed by production expenses, and thanks to our efficient production technologies, our systems are available at competitive price points.

Moreover, water purifiers command varying operational expenses. This includes power bills, manpower, repairs, and maintenance. The operating costs often differ depending on the type of equipment and the feed water being purified. Feedwater characterized by low contamination tends to be relatively cheaper to purify than highly polluted water. Purifying brackish water using reverse osmosis averages 0.25 to 0.66 dollars per cubic meter. However, desalinating a similar amount of seawater, which is more saline, averages 0.79 to 2.38 dollars.

Purifying 1000 gallons of raw water using multi-stage flash (MSF) distillation, presently does not exceed 3.79 dollars while water deionization ranges between 0.3 and 0.5 dollars. Procure your purified water generation system from NEWater today at pocket-friendly prices and save up to 50% on operational costs.

➣Which Pretreatment Systems Are Commonly Used in Purified Water Systems?

Water purification is mainly accomplished in three stages, pretreatment, primary treatment, and post-treatment. Pretreatment commences the water purification process by eradicating aggressive impurities to mitigate fouling of the primary equipment. The following are pretreatment systems frequently exploited in water purification applications.

● Chemical dosing systems.

Chemical dosing systems automatically inject chemical reagents into the feed water to expel certain impurities.  Some of the reagents injected using chemical dosing systems include chlorine and antiscalants. Antiscalants are used to lower the level of water hardness in the feed water while chlorine is injected to kill harmful microorganisms.

● Sediment filters.

Sediment filters are deployed to capture sediments and other suspended solids that might clog membrane filters. Varying filters including multimedia, pressure sand, and quartz sand filters can be used as pretreatment solutions for water purifiers.

● Water softeners.

Feedwater with excessive amounts of calcium and magnesium (hardness-causing ions), can cause scaling in pipes and metallic surfaces. To mitigate this, water softener systems are deployed to pretreat the feed water. The most effective and commonly utilized water softener systems are ion-exchange water softeners. Other pretreatment systems include;

• Ultrafiltration, nanofiltration, and microfiltration filter systems.
• Iron removal filters.
• Ion exchange filters.

➣Do Purified Water Systems Necessitate Post-Treatment?

The need for post-treatment or polishing is determined by your desired purity levels. Post-treatment gets rid of the impurities left in the water after pretreatment and primary treatment. Let us look at some post-treatment processes that can elevate the quality of your purified water.

● UV water disinfection.

This technology seeks to nullify the threat posed by microbial contaminants. UV water sterilization destroys bacteria, viruses, and other microorganisms using germicidal rays. Chemicals are hardly used hence the taste and odor of your water remains unaltered.

● Remineralization.

Remineralization is primarily used to post-condition purified water generated using reverse osmosis systems or water deionizers. It adds essential minerals to the purified water. It is often utilized when purifying drinking water.

● Activated carbon filtration.

In case your water has an unpleasant odor or taste, you can subject it to activated carbon filtration. This technology exploits activated carbon filters, which function through adsorption to extract organic chemicals responsible for awful tastes and odors. It also removes volatile organic compounds (VOCs), pesticides, and chlorine.
